Abstract (en)
[origin: WO8702380A1] Low-ethanol wines and other alcoholic beverages are produced by treating ordinary alcoholic beverages with novel membrane extraction methods. Semipermeable membranes and extraction fluids comprised either of a non-toxic, water-immiscible organic solvent or an aqueous solution of a low-molecular-weight but membrane-impermeable solute are used under mild conditions to selectively extract ethanol from alcoholic beverages, while leaving substantially intact the complement of other organic constituents that contribute to the color, aroma, and taste of the beverage. The methods disclosed may be adapted to continuous processing of alcohol-containing beverages, in which an ethanol-rich product is continuously recovered from the organic or aqueous extraction fluid and the latter is continuously regenerated and subsequently recycled to the membrane extraction unit.
